To all whom 'it may concern.'

d Be it known that I, JOSEPH H. GLAUBER, a 'citizen of the United States, residing at Cleveland,- in the county of Cuyahoga and State of Ohio, have' invented new and-useful Improvements in Coupling-Pipes, of which the following is a full, clear concise, and exact description, reference being had to the accompanying drawing, forming a part of this speciiication. A d

invention relates to coupling pipes such as are employed .in making .connetlon v betufeen service pipes and the faucets of bath tubs, wash basins and the like.

Ina patent granted to me February 14th,- 1905 No. 782,552, I have shown a cou ling pipe for open plumbing work for connecting the service pi with a faucet of afbath tub or wash basin, the pipe being madeof a single piece 'of tubing of substantially uniform cross-section from end toend, ,andgdesigned-to have its ends telescoped into a'service pipe and the Spud of the faucet -connected thereto. The coupling pi `of that patent possesses the advantage origen@ of a single piece of tubing and 1avoids the di sad\*antages of the threaded built-up cou 'pling pipes having numerous joints subjcctto leakage which'were universally used prior to theE invention of the coupling pipe of the above-mentioned patent. In view of the x4xfayct, lvliowever, that the single piece coupling pipe of the patent referred to is o f the same diameter throughout its length, such diam.-

l 'eteri'being that of the ends which telescope iuto;, tl1e service )ipe and faucet spud, it is I.confip'rziratively s ender and contracted and `does notpossess the massive and substantial appearance of-the full-size piping of the 4 builtlup style-of coupling pipe.

The object of the present invention is tol 5 provide a coupling pipe which possesses the advantages of thecoupling pipe of my `former.patent and at the same time has the massive and substantial a pearance of the builtfup coupling pipe. an which possees .g thefurther advantage, inasmuch as the body portion may be of the size of the built-up connections, of permitting the use of standard size threaded fittings, such asstop cocks, airl chambers, etc., sometimes used in the built-up connections, should it be desired to -employ the same with the coupling pipe.

f To this end my invention compris a im single piece coupling-pipe consistin of end portions of substantially the same iameter and a body portion of greater diameter than formed that it may telescopeinto the service pipe or the faucet Spud, as .the case may be, the pipe be` reversible end Ifor end s0 that whichever .en it is desired to have adjustable with respect to the partfwith -which it is to be connected may be inserted into said part, while that portion of the coupling pipe which is ,expose when the device is 1n use may be of the same orsubstantially the same size as the ordinary coupling pipe. I '-1 In the accompanying drawings-Figure 1 is a view, partially sectional, of vanielbow form of coupling p1 embed my invention, showing the4 rter arm ereof con but with the coupling pipe reversed, the arm being connected te the faucet trates a stralg ,my invention. .I Y l In the embodiment .of the invention illustrated in Fig. l, the couplingpipe is of the elbow pattern -and is made of a si le piece of tubing, in thatvi't'is free from. ]oints or t .coupling pipe .embodying viously the coupling pipe might be made up otherwise permanently secured together so as to be in eiect a single piece tube or pipe. The coupling pipe shown in'Fig. 1 is provided with arms of unequal length extending from the elbow, the longerl arm being 'designated l0 and the shorter arm 11- The traced in Figs. l 'and 2, the shorter arm 11 of vthe coupling pipe provided with a collar 15 at -the inner end of the reduced end 13 diameteras to readily telescope into the Spud on the 'coupling pipe or it may be developed from the pipe itself.A The' reduced endl? louer spu and the other arm tothe service pipe;l F r3 is a detail viewin pers ectivefof one en of the .co ling pipe; an Fig. Ll'illusof twolor more parts welded, br-azed, o rends l2 and 13 .of the'coupling pipe are oft heretofore mentioned, and

said ends, .each .of the "reduced .ends being so nected to'a faucets and the longer arm to a Service pipe; l1 ig. 2 is asimilar view v.

separable .connections between its ends.y Obico of the pipe, such reduced 'end being'of such at the other end oigthe coupling pipe is likewise of such diameter as to readily telescope into an ordinary. service pipe or faucet Spud, and in order to allow for the telescop- 1 ing of such end to the necessary degree to insure proper connection irrespective of the extent to which the end of-the service pipe may extend above the iioor or the height of 'the faucet from the end of the service.pipe,

, eiieh conditi-:nis vary indiiterentA installations, the reduced end 12 is of suc/h length to adapt the coupling pipe to a Wide variatie-n in the conditions mentioned;

l n F 1 the coupling pipe is shown conthe spud 1G of an ordinary faucet service pipe 17. The rear end of the faucet spud has an inwardly tapering seating portion, as is usual with such devices,

and in the tapered end tits a cone-sluipedA seat or gasket 18, which may be of rnbber or other suitable compressiblc material, including lead or other soft metal. This scat 18 is seated against the collar 15, and when the coupling nut- 19'of. the- `faucet which makes screw-threaded*engagement with the Spud 16 is screwed firmly against the collar, t e seat- 18 is forced-into thertapered space [between the reduced end of the pipe and ,the

and it is evident that the same may e extended into the service pipe for a greater .or` less distance, as required by existing -W'hen the nut 21 is tirmlf conditions, considerable latitude in this respect being afforded to meet the varying conditions of installation.

Surrounding the reduced end 12 of thel couplingpipe is a washer 2O of suitable inaterial, such aslead or other'sott metal, or even rubber, if preferred, this Washer-being so disposed as'to seat itself against the end of the service pipe.- `A coupling nut 21 en.- gages with suitable threads upon the exterior of the service pipe and between the inturned flange of this nut and the washer 20 may be inserted a metallic swivel washer 22. screwed down, the washer 20 is compresse and made vto ling the coupling pipe, a water-tight jointheing thus made. v

In Fig. 2 the coupling pipe is shown as reversed; that is, the end. 12 is inserted in the faucet spud and the end 13 in the service pipe 17, to adapt the coupling lpipe to other conditions than those shown in Fig. 1, as when the service pipe is brought up through the Wall or partition back of the Y basin or bath tub. When connectcdlunder such conditions, the seat 18 is placed on the end 12, which is then inserted tothe proper degree in the faucet Spud, and connected to such spud by a suitable nut 19 which engages the threads of thespud and, react-ing against the swivel washer 22, clamps the seat 18 against the tapering seat in the spud.-

The other end, or 13, enters the service pipe 17 and connection with such pipe is made by a suitable nut 21a which, reacting against the colla-r 15, compresses the washer 2O against the end of the service pipe.

In the particular form of coupling pipo shown in Figs. 1 and 2, the short arm 11 is oii'set laterally from the long arm 14, as shown in Fig. 3, to adapt the coupling' pipe to installations where the faucets are oit'sct laterally from the line'of the service pipes. This, however, is not material, ,as various modifications may be made without departing from the spirit of my invention. Nor is it essential that the pipe be of elbow pattern.

For `example, for certain installations the coupling pipe may be made straight, as shown in Fig 4. In this figure the enlarge-l body portion designated 14 is provided at one endwith'a reduced portieri 12a correspending to 12 of Fig. 1, and at the other end with, a` reduced portion 13a corresponding with the end 13.01AFig.. 1, the latter end bgein'galso provided with a collar 15a, similar to the collar loof Fig. 1. In other words,

the coupling pipe ofFig. 4 is similar to that of Fig. 1, except that it is straight instead of elbow form. This form of the con )ling pipe may be 'employed with certain sty es ot' faucets the spnds of which extend through the basin slab, and is connected up with the faucet and service pipe in the same manner as the coupling pipe shown in Fig. 1. As both ends'pf the pipe telescope into the parts and are securely held in place by means of the collar 15,-there is no danger of either end of the pipe blowing out. I

W'hen the coupling pipe of my invention .to which they are adapted to be associated,

is in use the enlarged body portion only is Y visible, except possibly a small part of the reduced end 12 thatv may be exposed nin the event that the installing conditions are such that the end 12 is not entirely telescoped into the pipe or faucet spud with which lit` is connected. Therefore, while all of the advantages'of the coupling pipe of my former patent. are retained, thc coupling pipe of the present application docs not havethe contracted appearance duc to the reduced diameter of the coupling pipe of that patent, but presents the massive and substantial api pearance of the built-up coupling pipe. Moreover, with the coupling pipe of my present invention it is possible to have the body of the coupling pipe of standard pipe sizes so that it may be 'cnt through and standard size stop cocks, air chambers, and other fittings may be inserted and permanently connected up in the body of the coupling pipe. l

The coupling pipe is preferablymade of annealed metal, so that it may be bent to conform to other conditions of installation,` such as misalineinent of the service pipes and faucets',

Having thus described my invention,what claini as new and desire to secure by Letters Patent, is

ll. As an article of manufacture, a single piece couplingl pipe comprising a body por- .1 tion provided with ends of reduced diameter adapted to telescope into and connectl a servl ice pipe ,and a faucet spud, the said body portion 'being of substantially uniform diameter between the reduced ends, a collar at one of the reduced ends and compression nuts f ortconnecting the ends to the service pipe and faucet Spud, one of said compression nuts coperating With said collar.

2. As an article of manufacture, a single piecelcoupling` pipe of elbow form having shorter arm 'having a collar at the inner end of its reduced portion, the body of the pipe between the reduced ends being of substan tially uniform diameter, and a compression nut for. each end of the pipe.

In Witness whereof, I have hereunto subscribed my naine in the presence of two Wit- DGS'SGS.
